@hawkeye10,
It's a statement not based on facts but on political bias.
What campaigning?
All Presidents have used the bully pulpit. It has never been campaigning until the right accused Obama of it.
As for the 'histrionics' statement, the only histrionics I see is the use of the word by the author to drive home a political point rather than sticking to the facts.
If it is a character flaw it is the author's character flaw and not the President's/
